IMPROVEMENT IN LOOMS.

Specication forming part of Letters Patent No. 141,907, dated August 19, 1873; application iiled June 18, 1873.

To all whom tmag/ concern:

Be it known that I, J oHN ZRGHER, of the city and county of Lancaster, in the State of Pennsylvania, have invented certain Improvements in Looms for Weaving, of which the following is a specification:

This invention relates to the arrangement and construction of separate shuttles, and manner of operating them, on a stitchingframe, singly, in pairs or groups, more or less remote, for the purpose of weaving or stitching intoor upon a gured fabric distinct ornaments or owers simultaneously with the mechanism which weaves the cloth. A J acquard is used to determine the gnres on the fabric in the ordinary way, as well as to determine the ilowers and ornaments stitched in by the shuttle.

The drawings illustrate my improved shuttle and manner of application to, and operation on, the stitching-frame.

Figure 1 is a part of an ordinary loom for weaving coverlids, to be supplied with an ordinary Jacquard, and stitching frame as shown in place. Fig. 2 is an enlarged view of a portion ofastitching-bar, with the parts used for operating and holding the shuttles. Fig. 3 shows the shuttle and spool detached.

The frame W is suspended from pulleys by a weighted cord, and is moved upl and down My invention consists in the application to the shuttleguides of springs to hold the shuttles in their grooves, when combined with other devices, as hereinafter described, for actuating such shuttles. The stitching-bar B is attached to the lower rail of the frame W, which extends across the loom, say, ninety-four inches, or the full width of a counterpane. At regular intervals there are inserted shuttle guides H, of an ovoid form, acuminated to a point below, and provided with a horizontal groove, h. These are inserted flush with the wood of the bar B, and project below the said bar, or are cast with a connecting-strip, N, and secured with screws to the bar B, as shown. The ends of the ilat springs E cover-the guides H about half-way, their ends being cut off directly over the grooves, so as to embrace or clamp the upper portion of the shuttles and allow the spoolsha-ft I to pass freely but closely under their edges. F shows the vibrating fingers, with their points f, which propel the shuttles. These ngers are centrally held between the strips or bars o o, on fulcrum-pins p, and act as levers, the upper endsbeing secured under a strip or bar, P, by pivot-pins p, to the shifting bar or rail A. This rail is connected with a hand-lever, R, affixed by a pivot to the stitching-bar B on the right hand of the center of the loom, and on motion being imparted to the lever R the ngers F f will be moved to the right or to the left, and when duly adjusted they will propel the shuttles G from one grooved guide, H, to the adjoining one on its right or left, back and forth at pleasure. The frame is also worked up and down, to make and secure the stitch, in combination with the ordinary shuttle, woot', and reeds used in weaving counterpanes, and the like, on the loom and Jacquard mechanism in common use. The shuttles G used are egg-shaped, and have a flange or tongue, g, centrally across the rear, which lits into the groove l1l in the guides H, and the portion above the spoolshaft I and spring K is clamped by the dat spring E. The spool M contains the yarn for the shuttle, while an open-looped guide-Wire, L, holds the yarn. The end G D simply shows the arm made for adjustingthat is, by means of a notched ange, d, for a vertical guidebar, b, on the loom, in which the stitching-bar is guided as it is raised and lowered with the frame. Thus the points of the shuttle-guides can be adjusted for the location of the ornaments to be stitched upon the fabric, while the throw ofthe iin gers is adjusted by a plate, a, on the back, and adjustable stops, so as to limit the action of the fingers on the shuttles to the exact distance.

This arrangement of a continuous series of guides, springs, and lingers, operated by a single lever, allows of bringing the separate shuttles in close proximity, singly, in pairs or groups, across the entire width. The spools of colored weft thread or yarn are readily changed on the shuttles. The stitching is performed, not by forming a loop t0 be cut, but firmly woven or stitched into the texture ot' the cloth simultaneously with the weaving of the same; and, in point of fact, is analogous to hand-stitching in its combination with the web and warp of the ordinary Jacquard or between strips o o P, with pivot-pins p on the stitching-bar B, in combination with the shifting rail A and lever R, substantially in the manner shown, and for the purpose described.
